IPE 220 vs IPN 220
- IPE 220 is 16 % lighter than IPN 220 (26.2 vs 31.1 kg/m).
- IPN 220 has 10 % higher strong-axis stiffness Iy.
- IPE 220 has 26 % higher weak-axis stiffness Iz, which governs columns and lateral stability.
- IPN 220 has 14 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, IPE 220 is the more efficient bending section (Iy/G: 106 vs 98 cm⁴ per kg/m).
